I started my model restoration with the compensating gear construction.

The heart of the c.g. consists of 2 pairs of standard steel bevel gears 1:4 16/64 M1,5

I machined the final gear from my old existing one ( z.70 M3 )

Milling the slots for satellites gears.

The steel disc is very large for my Proxxon milling machine !
